Answer:

Fossil of the hard-shelled organism which shows the surface contours giving the exact 3D shape of the organism is called a mold and cast fossil. Fossils are formed in water bodies where the sediments can be deposited over the dead and decayed organisms.  

When hard-shelled organism dies, still water plays important role in the formation of these fossils as: when water from sediment leaches our it decays the organic matter which creates void which is filled by sediment or mineral matter and the acidic water dissolves and breakdown the shell which gets surrounded by the mud or sand which hardens.

Thus, water plays an important role in the formation of mold and cast fossils.

Still waters allow for sediments to settle down on fossils without disturbance. This gives the minerals in the sediments time to perfuse in the fossils and petrify the fossil.  The sediments also settle on the fossils without disturbance, take the form of the fossil and get cemented forming molds.

How does science directly affect you? Where will what you have learned lead you next? PLEASE HELP ME RIGHT NOW!!!!!!!
Andru [333]

Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.
